Japanese Patent JP6876248
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an electrode assembly where a lamination electrode body is attached to a battery case cover, and lamination deviation is less likely to occur when inserting into the battery case body.SOLUTION: A battery assembly includes a lamination electrode body where a positive electrode and a negative electrode are laminated alternately while interposing a separator therebetween, and a case cover to which the lamination electrode body is attached via the collector terminals of the positive and negative electrodes. The lamination electrode body is provided, at at least a part of the face facing the case cover, with a pressure receiving part where the positions of the ends of the negative electrodes and the ends of the separators are arranged along the facing face.
